Describe the feature you would like

This is a followup from Telegram conversation: https://t.me/foundry_support/50555

Complex Scripts can sometimes require broadcasting a pre-signed transaction, just as we would do with cast publish.

For example, if I want to test Seaport using @0age's keyless deployment of IMMUTABLE_CREATE2_FACTORY (as outlined in Seaport deployment guide).

A the moment, the only alternative I could find is to use vm.ffi in this way:

    string[] memory args = new string[](5);
    args[0] = 'cast';
    args[1] = 'publish';
    args[2] = '--rpc-url';
    args[3] = 'http://127.0.0.1:8545';
    args[4] = '0xf87e8085174876e800830186a08080ad601f80600e600039806000f350fe60003681823780368234f58015156014578182fd5b80825250506014600cf31ba02222222222222222222222222222222222222222222222222222222222222222a02222222222222222222222222222222222222222222222222222222222222222';

    vm.ffi(args);

However, having a vm.publish(signetTX) cheat code can make this process much simpler.

Note: to avoid race conditions, the cheat code should return only after the inclusion of that signed tx into a block (or a revert if it is failed).

See #4931 for an initial implementation of this. I would definitely find this useful
